I have an Arri BL4s with no battery. My basic physics is woeful and as a result I'm getting a little confused as to what to get and I'm terrified of destroying the camera! .
According to Jon Fauer's book, the camera takes 12v, 7ah.
So presumably I just need a 12v 7ah lead battery, the sort you can easily pick up for not very much money? The only alarm bells that are going off in my head revolve around the fact that any branded camera battery seems to cost a lot of money. Am I missing something, or would one of these cheap batteries provide the exact same power as one of the more expensive ones?
On another note, how important is the amp-hour figure (7ah)? If I had a 12volt battery which delivered 14ah for example, would that be a problem or would that fry the motor?
Any help gratefully received!
